Emissions - ????????????????/

Took Hari's car in for it's third attempt at the MOT test but again it failed the emissions bit so the test was aborted.



CO running at between 4 and 5 depending on which tail pipe is being tested (between 4 and 5 not .4 and .5) which puts most of the usual culprits out of the picture.



Cat about 5,000 miles old.

Exhaust TT mk4.

New lambda.

New coil pack, plug leads and plugs.

New water temp sender.

And all sorts of odds and sods I can't remember.

Italian tune up.



So what is causing this massive over fueling-need some ideas before I break the damn thing.
